Trying to add the currency symbol to value using system.globalization

i am trying to add the currency symbol to totalvalue by using following code

using System.Globalization;

double value;
double totalValue = 0.0;            

foreach (DataRow row in reportData.Rows)
{
    if (double.TryParse(row["value"].ToString(), out value))
    {
        totalValue += value;
        RegionInfo rgi = new RegionInfo("en-UK");
        totalValue += Convert.ToString(string.Format("   CurrencySymbol:               {0}\n", rgi.CurrencySymbol));             
     }
 }

it was giving error can not convert type string to double would any one pls help me

Modified CODE:

       int count;
      int total = 0;
      double value;

      double totalValue = 0.0;




      foreach (DataRow row in reportData.Rows)
      {
        if (double.TryParse(row["value"].ToString(), out value))
        {
          totalValue += value;


        }

        if (!Overview && int.TryParse(row["mshipssold"].ToString(), out count))
        {
          total += count;
        }
      }

You need to do your totalling and then convert it to a string.

double totalValue;
foreach (DataRow row in reportData.Rows) {
  double value;
  if (double.TryParse(row["value"].ToString(),out value) totalValue+= value;
}
CultureInfo rgi = new CultureInfo("en-GB");
string totalValueCurrency=string.Format(rgi,"{0:c}", totalValue);

In answer to your modified question:

before before DataRow totalRow = reportData.NewRow(); insert the two lines

CultureInfo rgi = new CultureInfo("en-GB");
string totalValueCurrency=string.Format(rgi,"{0:c}", totalValue);

and then change

totalRow["value"] = totalValue;

to read

totalRow["value"] = totalValueCurrency;

However this might go horribly wrong if the datatype of your column is not string. You may be better of changing your report to do the formatting for you.

If you are using Microsoft Chart Control you may want this instead:

Modify this section of code

foreach (ChartArea chartArea in targetChartControl.ChartAreas)    {
  chartArea.Area3DStyle.Enable3D = true;
  chartArea.AxisX.LabelStyle.IsEndLabelVisible = true;
  // New Line Here
  chartArea.AxisY.LabelStyle.Format = "C";
}

You cannot store a string in a double - this will never work when totalValue is a double.

totalValue += Convert.ToString(string.Format(" CurrencySymbol: {0}\n", rgi.CurrencySymbol));

This line is a bit confused:

          totalValue += Convert.ToString(string.Format("   CurrencySymbol:               {0}\n", rgi.CurrencySymbol));

totalValue is a double and you're trying to add a string to it.
